Table 1. Troubleshooting Add Engine Coolant Level Sensor

Section 23.3.1
Check Sensor

Perform the following steps to check the sensor. ‪

  1. Unplug the ACLS/AECL Sensor. Start the engine.
  2. Plug in the diagnostic tool. Read codes.
    1. If code 13 (111/6) displays, refer to "23.3.2 Check for Short" .
    2. If code 16 (111/5) displays, replace the AECL Sensor and test the results. Refer to "23.3.4.1 Verify Repair" .

Section 23.3.2
Check for Short

Perform the following steps to check for a short:‪

  1. Turn ignition OFF and unplug the ACLS/AECL Sensor module.
  2. Measure the resistance between cavities A and B of the ACLS/AECL Sensor connector. See Figure "Add Engine Coolant Level Sensor Installation" .
    1. If the measured resistance is greater than 10 Ω, refer to "23.3.3 Check for Voltage" .
    2. If the measured resistance is less than 10 Ω, V 37 and ground wires are shorted. Repair or replace the wires and test. Refer to "23.3.4.1 Verify Repair" .
    3. Click to see this graphic in a separate window

Section 23.3.3
Check for Voltage

The ACLS/AECL Sensor probe is connected to a separate module when used for a Coolant Level Low Lamp. The module provides an output to drive an indicator light on the dash. ‪

Perform the following steps to check for voltage:‪

  1. Turn ignition ON.
  2. Measure voltage between cavities E and C of the ACLS/AECL Sensor module connector. See Figure "Add Engine Coolant Level Sensor with Dash-mounted Lamp" .
    Click to see this graphic in a separate window

    Figure 2. Add Engine Coolant Level Sensor with Dash-mounted Lamp

    1. If the measurement is 11.0 volts or greater, refer to "23.3.4 Check for Open Signal" .
    2. If the measurement is less than 11.0 volts, determine the reason for the loss of ignition voltage.

Section 23.3.4
Check for Open Signal

Perform the following steps to check for open signal:‪

  1. Turn ignition OFF.
  2. Unplug the engine harness connector.
  3. Measure resistance between cavities D and G of the ACLS/AECL Sensor module. See Figure "Add Engine Coolant Level Sensor with Dash-mounted Lamp" .
    1. If the measured resistance is greater than 10 Ω, replace the ACLS/AECL Sensor module; then, refer to "23.3.4.1 Verify Repair" .
    2. If the measured resistance is less than 10 Ω, the signal wire is shorted to the battery ground wire. Repair the short; replace the wire. Refer to "23.3.4.1 Verify Repair" .
Section 23.3.4.1
Verify Repair

Perform the following steps to test the repair:‪

  1. Connect all the removed connectors.
  2. Start and run the engine for 5 minutes.
  3. Plug in the diagnostic tool.
  4. Read the active codes.
    1. If no codes display, the repairs are complete.
    2. If code 13 displays, troubleshooting is complete; review these steps to find the error.
    3. If any codes other than code 13 display, refer to "18.3 First Step for Diagnosing a Fault Within the DDEC System" .
